EMANUEL M. VINTERS, OF SQUARETOP, PENNSYLVANIA.

VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 779,754, dated January10, 1905.

Application led March 28, 1904. Serial No. 200,392.

-To all whom t may concern:

Be it known that I, EMANUEL M. WINTERs, a citizen of the UnitedStates,residing at Squaretop, in the county of Vyoming and State ofPennsylvania, have invented certain new and useful Improvements inVehicle-Brakes, of which the following is a specification.

The improvements in vehicle-brakes which form the basis of my inventionrelate particularl y to the manner of mounting' the operatingmechanisms, whereby upon application thereof the strain of the brakingaction will not force the wheels rearward and affect the rigidity ofthemounting of the axle carrying' same relative to the vehicle-body.

It is well known that in vehicles in which the vehicle-body is supportedupon the axles by means of elliptical springs the pressure of thebrake-shoes against the wheels tends to loosen the bearing connectionsof' the spring with the axle upon which said wheels are mounted, andthus the axle gets a certain amount of play as regards the shoes, verydetrimental to the proper working of the brakes. rl`hus when the vehicleis ascending grade the axle plays forwardly against the brake-shoes,retarding movement to some extent, and when going downgrade the play ofthe axle is such as to cause the wheels to move away from thebrake-shoes to such an extent that in some instances it is impossible toapply the brakes.

My invention aims to obviate the foregoing disadvantages of constructionand also to provide novel operating means whereby comparatively smallamount of power is necessary to effect a very eflicient braking action.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreecting the result reference is to be had to the following descriptionand accompanying drawings.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in whichH Figurel is a side elevation. tion on the line 2 2 of Fig. 1.

Fig.l 2 is a sec- Fig. 3 1s a detached perspective view of the brakemechanism. Fig. 4 is an under side perspective view of the mainoperating -lever and adjacent mechanism. Fig. 5 is a vertical section ofthe brake-shoe. Fig. 6 is a detail perspective view, parts separated, ofthe brake-shoe. Fig. 7 is a horizontal section of the brake-shoe. Fig. 8is a detail view showing more clearly the mounting of the guide membersupon the supporting-arms.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Though my brake structure is especially adapted for use upon cabs orlike vehicles, it will be understood that it may be advantageouslyapplied to any type of wagons or vehicles now in common use. rPheinvention is shown in its adaptation as a manually-operated brake,though any suitable power may be utilized to apply the brakes inconnection with the operating means hereinafter to be described.

In the drawings, l indicates a wagon-body partiallybroken away, whichlatter is mounted upon a rear axle 2, provided with the groundwheels 3.The wagon-body is supported upon the axle 2 by means of a spring L ofthe usual elliptical type commonly seen upon vehicles. Secured to therear portion of the body l of the vehicle is disposed a curvedsupporting-bar 5, the front end of which is carried bylaterally-adjustable supporting members 6, secured directly to thewagon-body. rlhe supporting members 6 are disposed transversely of thewagon-body 1, being secured thereto by means of fasteningbolts 7 or thelike. The fastenings 7 pass through longitudinal slots 8 inthesupporting members 6, so as to admit of a lateral sliding adjustment ofsaid members for purposes which will be set forth hereinafter. The innerends of the members 6 are likewise slotted, and the fastening memberwhich secures the inner ends together constitutes the means for securingthe curved supporting-bar 5 upon the wagon-body. The supporting-bar 5has its rear portion extended downwardly and formed with bifurcatedextensions 9, projected IOO downwardly therefrom. The extensions 9 havepivoted to the end portions thereof the supporting-arms 10, the innerends of the supporting-arms being suitably secured by a pivotalfastening to the end portions of the extensions 9. The supporting-arms10 are of approximately T form, being' provided at their outer ends withintegral guide members 11. Brake-bars 12 are slidabl y mounted upon theguide members 11 of the supportingarms 10, and these bars directlysupport the brake-shoes 13. Guide projections 141 extend upwardly fromthe guide members 11 and direct the movement of the brake bars 12, whichlatter are longitudinally slidable relative to the vehicle-body. Aslidable movement of the brake-bars effects thel movement of the brakeshoes toward and from the wheels 3, and the said shoes are mounted uponangular extensions 15 of the said brake-bars.

Projecting downwardly from the rear end portion of each guide member 11is a bracket 16, which is of approximately U form in elevation, and thearms 17 of the brackets are provided with openings through which anadjusting-bar 18 passes. Each adjusting-bar -18 is longitudinallythreaded and is carried by the axle, being' pivoted to a pivot member19, secured to the said axle. Nuts 2O are adjustably disposed upon theadjusting-bar 18 and are adapted to cooperate with one of the arms 17 ofthe adjacent bracket 16 to fix the adjustment of the supporting-armwhich carries the brake-bar adjacent thereto. From the foregoing it willbe noted that the supporting-arms, which are pivotally mounted upon thebifurcated extensions of the bar 5, are adapted for adjustment by meansof the adjusting-bars 18, so as to regulate the amount of movementimparted to thebrake-shoes 13.

Depending from the front end of each of the guide members 11 of thesui'iporting-bars 10 is a lug 21, secured to the adjacent end of thesupporting member 6 by means of a swivel member 22. r1`hc supportingmembers 6 being rigidly secured to the body of the vehicle and theadjusting-bars 18 being likewise permanently, though pivotally, mountedupon the axle 2, it will therefore be noted that the guide members 11,together with the members 18 and 6, constitute rigid connecting meansbetween thc-vehicle-body and the axle. Adjustment of the nuts 2O uponthe bar 18 will cause a pivotal movement of the adjacent supporting-arm10 to a certain extent, and a slight pivotal movement of thissupportingarm is likewise caused when the adjacent supporting member 6is laterally adjusted so as to movethe brake-shoe laterally.

The brake-bars 12 are actuated by means of horizontal levers 23, whichare pivoted at points between their ends to respective supporting-arms10, their outer ends being connected with the said brake-bars. r1`heinner ends of the actuating-levers 23 are provided with longitudinalslots 24, anda connecting-bar 25 is secured to the slotted end portionsof the levers 23 by means of a pivotal fastening' 26. The connecting-bar25 connects the inner ends of the levers 23 with a compensating lever27, which latter is mounted in a relative vertical position upon thecurved supporting-bar 5. The upper end of the compensating lever 27 isprovided with a toothed segment 28, which latter meshes with teeth 29,formed upon ,the bar 5. The upper end of the lever 27 is receivedbetween spaced guide-bars 30 of the supporting-bar 5, and atransverse-pin 31 prevents displacement of thc segment 28 fromengagement with the toothed portion of the bar 5. The compensating lever27 is virtually pendent from guide-bars 30, and the lower end of saidlever is connected, by means of a flexible connection 32, to the mainpower or operating lever 33. The power-lever 33 is mounted upon theforward portion of the vehicle-body in a position convenient foroperation either by foot or hand of the driver lof the vehicle. Themounting of the power-lever is peculiar in that same is such as to givea maximum degree of braking connection with a comparatively smallmovement of the said lever. The lever 33 is slidable upon thevehicle-body, passing through a slot 311. The lever'33 is supported by arack-bar 35, and the lower end of this lever is also provided with anintegral toothed segment 36. The rack-bar 35 is secured to the lowerends of spaced plates 37, which latter receive the segment 36 of thepower-lever 33 therebetween. The plates 37 are secured to the under sideof the vehiclebody in the spaced relation aforementioned and form guidescooperating with the segment 36 to direct and properly position thelever 33 in its slidable movement. A pivoted bar 38 is secured at oneend to the lever 33, and the other end of this bar passes through theslot 34, being provided with a swiveled link 39, to which the flexibleconnection 32 is directly connected. The pivoted bar 38 has a relativelyhorizontal movement as regards the vehiclebody, and a transverse pinL10, passing through the depending end of this bar, moves inlongitudinal guides 11, carried by the vehicle-body and suitably securedto the latter adjacent the spaced plates 37. The connection 32, which issecured at one end to the link 39, passes about pulleys 42 as it extendsto the point of connection with the compensating lever 27. Thedisposition of the connection 32 will of course be varied dependent uponthe class of vehicles to which the brake mechanism is applied. Becauseofthe mounting of the powerlever 33, the same not only gets a pivotalmovement, but a slidable adjustment adapted to greatly increase thelength of its pivotal movement, and thus the relative power of thismember is greatly increased in quickly applying the brakes.

The brake-bars 12 are normally held in positions upon thesupporting-arms 10 so that the brake-shoes are spaced from the wheelswith which they engage. The means for holding the shoes in the positionindicated above comprises a spring 43, which connects the lower portionof the compensating lever 27 and the axle 2. The spring 43 normallyexerts a tension sufficient to hold the shoes 13 away from the wheels,the actuating-levers 23 -being acted upon by the spring 43 to accomplishthe above through the medium of the compensating lever 27 abovementioned. rIhe brake-shoes embody a specific structure comprising' theblocks 44 and removable rubbers or friction-plates 45. The brake-blocksare provided with openings which receive the angular extensions 15 ofthe brake-bars 12, and these blocks are provided upon their inner sideswith lianged plates 46. The rubber or friction-plate 45, which is to besecured to the brake-block, is provided upon its sides with longitudinalgrooves 47, and one of the grooves of each rubber receives the flange 49of the plate 46 of the adjacent block 44. A clamp-plate 48, tlanged, asshown at 49, is secured upon the outer side of each block 44 by meansoi' nuts 50, adapted to be screwed upon the end of an adjacent bolt orbolts 55. The liange of each clamp-plate engages in one of the groovesof the adjacent rubber 45, and the latter is thus securely heldy betweenthe iianges 49. Removal of the clamp-plate admits of ready displacementof the rubber should same be worn or unserviceable. A spring 51 iscarrie-d by each block 44 and engages the brake-bar which carries saidblock.

The brake parts are adapted for application to different-sized vehiclesbecause of the ad j ustability particularly of the supporting members 6and the supporting-arms 10. The actuating-levers 23 admit of thisadjustment because of their construction, and the adjusting-bars 18 areimportant members in their coperation to fix the supporting-arms at anascertained adjustment. The adjusting members also hold the axle rigidas regards the wagonbody and prevent any sagging or play of the axle.The various parts may be quickly removed or secured in position bypersons having ordinary mechanical skill.
